When deciding on a commercial roofing system, you’ll need to consider several factors. These factors include the type of business you run, the climate of your area, and the construction of the building. The final decision will depend on the needs of the building and its tenants. However, there are some common roofing options to choose from, such as EPDM, Modified bitumen, and Metal.
Build-up roofs
A built-up roof is a versatile type of roofing material that can be applied to a variety of surfaces. This material provides excellent waterproofing and is suitable for low-slope or flat roofs. It is made of heavy materials such as tar and gravel that are packed to form a dense layer. While this type of roofing is low-maintenance, it is not energy-efficient and may not withstand adverse weather conditions.
Modified bitumen
Modified bitumen was first used in commercial roofing in Europe during the mid-1960s. Prior to this, buildings had built-up roofing systems, which included alternating layers of asphalt and fabric with a top layer of gravel. These systems were bulky, expensive to install, difficult to repair, and often did not hold up to harsh temperatures. Modified bitumen, which integrates fiberglass and polymers into a single membrane, was developed to remedy these problems.
EPDM
EPDM flat roofing is an environmentally friendly option for flat roofs. Compared to other roofing materials, it has a long life span, is affordable and easy to install. In addition to these advantages, EPDM is recyclable, giving used rubber tires a second life.
Metal
Metal flat roofing is one of the flat roofing most popular roofing materials today. Compared to other types of roofing, metal is durable and can last up to 35 years in good conditions. It reflects heat and wicks away moderate moisture. However, in more wet climates, metal can experience corrosion problems. Some manufacturers offer a 40-year warranty on their products.
Liquid coatings
Liquid coatings for flat roofing are a relatively new technology. They provide a seamless, waterproof, and UV-resistant covering for roofs. Although they may not last as long as traditional roof coatings, they are still worth considering for their attractive aesthetic appeal and solid protection against leaks. Additionally, the water-based topcoats don’t chip or peel over time and are highly resistant to cold temperatures.
Green roofs
If you are looking for an environmentally-friendly option for your building, you should consider green flat roofing. This roofing material has a number of benefits. The vegetation is low-maintenance and self-sustaining, and many types of plants are appropriate for this application. This type of roofing is perfect for flat or large sloped roofs. The plants chosen for this purpose are usually drought-tolerant and require little or no irrigation.
